Engineering Wed, 27 May 2015 10:20:38 EDTnews351940830Using composite material samples, NRL scientists predict aspects of F/A-18 performanceThe U.S. Naval Research Laboratory (NRL) has built a robot to pull, bend, and twist samples of the composite materials used to build F/A-18s and other aircraft. Dr. John Michopoulos leads the project. With a machine that can, as he says, "Measure so much more than anybody else," and some very advanced math, he can "create a theory that is consistent with all these experiments that we made, and works for all scales." He predicts how the materials will perform when made into large structures and used over many years.http://phys.org/news/2015-04-composite-material-samples-nrl-scientists.html

In the cell walls of many plants, wrinkles allow expansion without strain. Finally, the inner lining of arteries contain wrinkled lamellae that can be indicators of coronary heart disease, and can serve as markers for the condition.http://phys.org/news/2013-04-scientists-guidelines-smart-composite-materials.html

Desalination plants can convert seawater to drinking water. Yet these plants require pipelines made of a special kind of steel or titanium – expensive material that is growing increasingly difficult to procure. Heat-conducting polymer composites may soon replace titanium altogether. http://phys.org/news/2012-10-accessible-material-seawater-desalination.html

Nanomaterials Tue, 14 Feb 2012 10:27:29 EDTnews248437631Explosive composite based on nanoparticles and DNA could be an energy source for embedded microsystemsA solid explosive with an energy density equivalent to that of nitroglycerine: this is the composite material produced by researchers at the Laboratoire d'Analyse et d'Architecture des Systemes (CNRS) in Toulouse, France, using an innovative production process that brings nanoparticles into contact with strands of DNA. These strands then "assemble" the various kinds of nanoparticles used. The released energy and ignition temperature of the new explosive are among the best ever described in the literature. The explosive could thus be used as an energy source to power embedded systems, both in space and in the environment. This innovative material is the subject of a paper published online in the journal Advanced Functional Materials.http://phys.org/news/2011-11-explosive-composite-based-nanoparticles-dna.html
